What is the right amount of insulation to put on the exterior of a home?
I have a home about 3000 sq. the top is about 1700 and the rest in the basement, being a cinderblock home with a 2 foot over hang. I studed my inner wall, I put R13 fiberglass and sheet rock, then on the outside I tared the out side and filled most of them with cement a few have insolation very few.
Shoud I put styrofoam board then tar board chicken wire then stuco then paint with elastromeric/ sand mix, all to keep out heat. Styrofoam or no Styrofoam is the question. is it worth the cost or am I going over board?
